PHP 5.1.2. Release Announcement

The PHP development team is proud to announce the release of PHP 5.1.2.
This release combines small feature enhancements with a fair number of
bug fixes and addresses three security issues. All PHP 5 users are encouraged to
upgrade to this release.

The security issues resolved include the following:

HTTP Response Splitting has been addressed in ext/session and in the
header() function. Header() can no longer be used to send multiple
response headers in a single call.

Format string vulnerability in ext/mysqli.

Possible cross-site scripting problems in certain error conditions.

The feature enhancements include the following notables:

Hash extension was added to core and is now enabled by default. This
extension provides support for most common hashing algorithms without
reliance on 3rd party libraries.
